Hydroxyéthylcellulose (HEC) Détails

Hydroxyethyl Cellulose (HEC)

Hydroxyethyl Cellulose, HEC

CAS NO 9004-62-0

Product Description

Hydroxyethyl Cellulose is a non-ionic water-soluble cellulose ether. It has the appearance of a white powder and is non-toxic, tasteless, and soluble in hot and cold water.
HEC has a very wide range of viscosity, and the product has very good transparency and biological stability. Compared with general HEC, it has better thickening, water retention and leveling properties. It has excellent performance in water-based coatings and oil drilling applications. At the same time, HEC is also widely used in agriculture, building materials, PVC polymerization, textile industry, cosmetics and detergents and other daily chemicals.

Introdution

HEC is a white or light yellow odorless, tasteless and easy-flowing powder. As a non-ionic surfactant, hydroxyethyl cellulose has thickening, suspending, bonding, floating, filming, dispersion, and water retention In addition to providing protective colloids, it also has the following properties:
HEC is soluble in hot or cold water, and does not precipitate at high temperature or boiling, so that it has a wide range of solubility and viscosity characteristics, and non-thermal gelling;
It is non-ionic and can coexist with a wide range of other water-soluble polymers, surfactants, and salts. It contains high-concentration electrolyte solutions.
The water retention capacity is twice that of methyl cellulose, and it has better flow regulation.
Compared with the recognized methylcellulose and hydroxypropyl methylcellulose, the dispersing ability of HEC is poor, but it has strong protective colloid ability. Uses: Generally used as a thickener, protective agent, adhesive, stabilizer, and additives for preparing emulsions, gels, ointments, lotions, eye clearing agents, suppositories and tablets, and also used as hydrophilic gels and skeletons Materials, preparation of matrix-type sustained-release preparations, and can also be used as stabilizers in food.
